Answer:

(3,-1)

Explanation:

2x -7y = 13

3x+y = 8

Multiply the second equation by 7

7(3x+y) = 7*8

21x +7y = 56

Add this to the first equation to eliminate y

2x -7y = 13

21x +7y = 56

-----------------------

23x = 69

Divide each side by 23

23x/23 = 69/23

x = 3

3x+y = 8

3(3) +y = 8

9+y = 8

Subtract 9 from each side

9-9 +y =8-9

y = -1

(3,-1)
